Checking colors in your document
Printed colors may not match the colors that were displayed on your monitor. For
example, an object that looked red on-screen may now look orange. At this point, you
need to correct any color problems in your artwork. You should also verify that your
monitor has been characterized, as described in
page 353.
If your document is color managed, you can preview how a color will appear when repro-
duced on a particular output device. (See
Types of colors you can use, and how they are separated
You can color artwork with process colors, spot colors, or a combination of both. For infor-
mation on your color choices, see
page 305.
When printing separations, you can convert spot colors to their process color equivalents
so that they will be printed on the CMYK plates. (See
colors" on page 423.)
Using process colors that don't need trapping
You can avoid the need for trapping by designing your document in such a way that your
use of colors eliminates the possibility of misregistration. You can prevent misregistration
by making sure that abutting process colors have common inks. For example, if you
specify a dark purple stroke with a vivid red fill, they will both contain a significant
percentage of magenta. The stroke's and fill's common magenta will print as a single area,
so that if misregistration occurs in the other process inks, the magenta printing plate will
make any resulting gap hard to see.
Printing gradients as separations
Consider the following when producing separations for documents with gradients:
A gradient created in InDesign that contains a combination of spot and process colors
•
will be separated onto both the process and spot plates.
A gradient that contains process colors will be separated onto the process plates.
•
A gradient that contains two tints of the same spot color will be separated onto a single
•
spot color plate.
To create a gradient that separates on one piece of film between a spot color and white,
•
create a gradient fill between the spot color and a 0% tint of the color.
If you create a gradient between two spot colors, you should assign different screen
•
angles to those spot colors in the Separation Setup dialog box. This is because if two
spot colors have the same screen angle, they will overprint each other. If you're not sure
what the angles should be, consult with your prepress service provider. (See
